Tony, that would be your choice to use XS-0.7, please don't put words in
my mouth, I would use the soon to be released XSCE-0.4 on the same

I have, XS on F11/F14 and I disagree, it sure does as the underlying OS
evolves, your customisations have to keep up, rpms may need to be
re-compiled and the general adapting to the changes in the OS.

or adding Django, content, or anything else someone wanted to pay for.

I think re-spinning the install iso is not that hard but you may need
more than one CD or switch to the DVD format to fit all the needed rpms.

I agree a fully offline install method is needed.

You better have your ducks in a row when it comes to internet email, you
can become subject to rbls and other such anti-spam measures by the isp
or hosting service of the people you might what to email. The email
subject needs to be fully thought out and ongoing support is required.

Doesn't matter which 'product' you choose, you'll need people with some
sysadmin and diagnostic skills to deploy those servers in the field and
that is not free.
